Recent research shows that indoor air is often 2 to 5 times more polluted than outdoor air, which is why you should keep the air in your home as healthy and clean as possible. You might not be getting a good night's sleep because of the pollutants in the air you breathe. The Austin HealthMate+ Jr not only removes particulate matter like smoke, dust mites, pet dander, mold spores, germs, viruses, and pollen, it will even remove volatile organic compounds (VOCs) that come from such sources as cleaning solutions, carpets, paints, building materials and formaldehyde and toxic gasses. Four stages of filtration ensure you are breathing clean air: First is a "large-particle" pre-filter to trap dust, hair, and pet dander; this filter is designed to be vacuumed rather than replaced. Second is a "medium-particle" pre-filter which traps mold, spores, and pollen. The third line of defense is 30 sq ft of medical-grade true HEPA filtration, which removes micro-organisms like bacteria and viruses. Finally, 6.5 pounds of military-grade activated carbon and zeolite removes chemicals, gasses, and odors. Most air filters sold in stores do not remove gaseous VOCs, and the electrostatic cleaners emit harmful ozone. The machine has four casters for easy mobility; move it from room to room to keep breathing clean air.
